FEATURES
DESCRIPTION
D MICRO-SIZE, MINIATURE PACKAGES:
The OPA237 op amp family is one of Texas Instruments’
MicroAmplifier series of miniature products. In addition
to small size, these devices feature low offset voltage, low
quiescent current, low bias current, and a wide supply
range. Single, dual, and quad versions have identical
specifications for maximum design flexibility. They are
ideal
for
single-supply,
battery-operated,
and
space-limited applications, such as PCMCIA cards and
other portable instruments.
− Single: SOT23-5, SO-8
− Dual: MSOP-8, SO-8
− Quad: SSOP-16 (Obsolete)
LOW OFFSET VOLTAGE: 750µV max
D
D WIDE SUPPLY RANGE:
D
D
− Single Supply: +2.7V to +36V
− Dual Supply: +1.35V to +18V
LOW QUIESCENT CURRENT: 350µV max
WIDE BANDWIDTH: 1.5MHz
OPA237 series op amps can operate from either single or
dual supplies. When operated from a single supply, the
input common-mode range extends below ground and the
output can swing to within 10mV of ground. Dual and quad
designs feature completely independent circuitry for
lowest crosstalk and freedom from interaction.

Single, dual, and quad are offered in space-saving
surface-mount packages. The single version is available
in the ultra-miniature 5-lead SOT23-5 and SO-8
surface-mount. The dual version comes in a miniature
MSOP-8 and SO-8 surface-mount. The quad version is
obsolete. MSOP-8 has the same lead count as a SO-8 but
half the size. The SOT23-5 is even smaller at one-fourth
the size of an SO-8. All are specified for −40°C to +85°C
operation. A macromodel is available for design analysis.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not implied.
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

SBOS057A − OCTOBER 1996 − REVISED FEBRUARY 2007
APPLICATION INFORMATION
OPA237 series op amps remain stable with capacitive
loads up to 4,000pF, if sinking current and up to 10,000pF,
if sourcing current. Furthermore, in single-supply
applications where the load is connected to ground, the op
amp is only sourcing current, and as shown Figure 1, can
drive 10,000pF with output currents up to 1.5mA.
OPA237 series op amps are unity-gain stable and suitable
for a wide range of general-purpose applications. Power
supply pins should be bypassed with 10nF ceramic
capacitors.
OPERATING VOLTAGE
100k
OPA237 series op amps operate from single (+2.7V to
+36V) or dual (±1.35V to ±18V) supplies with excellent
performance. Most behavior remains unchanged
throughout the full operating voltage range. Parameters
which vary significantly with operating voltage are shown
in typical performance curves. Specifications are
production tested with +2.7V, +5V, and ±15V supplies.

OUTPUT CURRENT AND STABILITY
VS = +2.7V
OPA237 series op amps can drive large capacitive loads.
However, under certain limited output conditions any op
amp may become unstable. Figure 1 shows the region
where the OPA237 has a potential for instability. These
load conditions are rarely encountered, especially for
single supply applications. For example, take the case
when a +5V supply with a 10kΩ load to VS/2 is used.
